But if no space was found, let the position remain 0. Note: The SUBSTR () and MID () functions equals to the SUBSTRING () function. Find the position of the first space in the reversed substring. The SUBSTR () function extracts a substring from a string (starting at any position). Then the necessary steps could be: Take the leftmost len characters of str. Note that to get the number of characters of a string, you use the CHARLENGTH () function instead. Therefore, the result of the LENGTH () function is based on the current character set of the string. The difference of the result between multi-byte safe functions, like CHARLENGTH() or CHARACTERLENGTH(), and LENGTH() function especially relevant for Unicode, in which most of the characters are encoded in two bytes or relevant for UTF-8 where the number of bytes varies. Let str be your string and len the initial position to cut at. LENGTH (string) The LENGTH () function takes a string argument and returns its length measured in bytes. MySQL is ideal for both small and large applications. On windows without SSL enabled there is an PHP deprecation message: Deprecated function: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in drupal_random_bytes() (line 2351 of /includes/bootstrap.inc). MySQL LENGTH() function measures the string length in ‘bytes’ which means that it is not multibyte safe. MySQL is a widely used relational database management system (RDBMS).
